R&D Report 1995-06 : Lightweight partitions having improved low frequency sound insulations. G.D. Plumb The sound insulations were measured of a range of single, double and triple leaf partitions. For the single leaf partitions, a staggered stud configuration was used. For the double and triple leaf partitions, the configuration of the boards was different from that in the conventional Camdens. At low frequencies, the partitions tested generally had higher sound insulations than comparable metal-framed Camdens. They also had higher sound insulations at low frequencies than comparable all-plasterboard partitions having the same numbers of layers of boards as in the metal-framed Camdens. The partitions will be suitable for use in studio constructions where lightweight partitions would previously have been ruled out on sound insulation grounds. This should enable considerable savings in construction costs.
